My 530e reaches 40K service. I took it to the dealer yesterday. The advisor texted me later I. The day telling me the 4 original Hankook tires need to be replaced due to wear. The same tires go for $1500 plus $215 alignment. I have the tire and wheel warranty. If I opt to get the tires installed at Costco, would that void the warranty in the future?

I am surprised your BMW has Hankook tires as originals. I had never heard of BMW using them as OEM installed. But just because I have never heard of it doesn't mean it isn't possible. You might check the fine print of your tire and wheel warranty but I can't imagine Costco installed replacement tires wouldn't be covered, although I suppose they might want you to notify them of the replacement. And the brand shouldn't matter either. I personally prefer Michelin tires and Costco sells them. I have had Costco put them on several BMWs, although I don't have a tire and wheel warranty. For my Corvette Z06, I have also had TireRack ship a set of Michelins to an independent Tire Rack approved installed which owns a Hunter Revolution tire changer, which I consider a must for large low profile runflat tires on the big wheels some of our cars have. --Bob

Thanks for the info, Bob. I do have a follow-up question. Does run-flat tires really matter vs the regular tires? Last time I had a puncture on my run-flat and the entire tire needed to be replaced anyway.

Been discussed many times RFT will have more road noise plus the price point. I'm on original RFTs too and thinking to switch to regular summer tires aswell. What dealer are you using for the service.

[CnSky]

Whatever you do only buy BMW star marked tyres or you could experience vibrations.

I went through all that. Nightmare.

Trying to get the Michelin Primacy MXM3 with Costco. However, there is another "staggered fit" category of tires available which I don't know what that is.

As noted here, there has been much discussion and many opinions about Run Flat Tires; Search is your friend. Personally I am a big fan of runflats and have had them on all my cars for many years. The early years of run flats were terrible--Bridgestones on BMWs in the early 2000s got very hard very quickly and the dealers were replacing them under full or partial warranty. But today's runflats ride and handle much better. I have had one event with runflat and it did indeed require replacement of the tire. I was heading out to a dinner engagement with my wife and fairly near our destination I hit a jagged piece of concrete knocked off the nearby curb. All the lights on the dashboard lit up but we were able to drive to our destination, drive home and drive to the dealer the next day. There was a two inch gash in the tire and it had to be replaced, but it got me to where I needed to go without my being stranded or having to call a tow truck. I liked that. --Bob

staggered just means that there are 2 different sets of tires on the vehicle. the rear are wider than the front. The M550is come like that. Possibly the 540is with sport package and summer performance tires? not a 100% sure.

Staggered wheel/tire set-up means that you have slightly wider wheels in the rear. If you look at your exisiting tire sizes...if they are all the same, then you have a "square" setup. If the front and rear tires are different sizes...then you have a "staggered" set-up.

If you look at the tire inflation chart in your owners manual...you'll see all the tire sizes that BMW offered...take note that some rear tire sizes listed may have the same circumference/diameter...but the width and aspect ration is different than the front.

Here's a direct link to one of the online part database sites and it is directly to the G30 WHEEL diagrams. If you click on the diagrams...you'll see that some of them have different size wheels for the rear...and you can see their specs vs the front wheel. You can also see the tire sizes BMW recommends for the various wheel set-ups: https://bimmercat.com/bmw/en/search/...0iX+B46/USA/36

I also have never heard that BMW used Hancook as an OEM supplier in the US. In terms of the dealer telling you that yor W&T warranty will be void if you don't buy from the dealer is BS. The W&T warranty isn't even written by BMW. It is aftermarket and can be purchased outside the dealer through banks, for example. So that makes no sense. There is nothing in the language of my Allstate plan that says I have to get tires from a BMW dealer.

Now all this said, I would only use the dealer or a reputable BMW independent shop for mounting tires. Tire chains, Costco, etc. are minimum wage hacks. They will scratch and damage your wheel. Pay the dealer a few hundred more for starmarked tires mounted properly.

Runflats are not supposed to be repaired. The selling point of runflats is the ability to drive on them when they are, well, "flat", i.e. no air. But the tire is trash after a few miles of driving on it. I believe runflats are rated for 50 miles when "flat". I actually pushed it to 50 miles on my F10 once as I was at a Casino 50 miles away. After 25 miles, you will be holding onto the steering wheel for dear life if on the front. It will be pulling hard.

I am not a fan of them. I went through 9 runflats in two years on that F10. I had insurance but it was a major inconvenience. See pot hole, can't react quick enough, hit pot hole, dash lights up like a Christmas tree.

The side walls of runflats is steel. This is why they don't compress and you can drive on them. At the same time, they don't compress naturally and absorb normal hits. This is why they bubble on the edge or on the seal to the rim after hitting a hole. This is also why they ride hard and are noisy.

Due to reinforcing structure of the sidewall of a tyre, RunFlats tend to be far less comfortable, showing early uneven wear (especially outer side in the front). I personally feel strange behaviour of a car when cornering with RFT and lack of comfort as a main complaint.
I will go for non-RFT in any way having a tyre repair kit (compressor + liquid sealant) instead.
The only advantage is RFT is that will allow to drive for a while when you have a puncture in it without destroying the tyre or having damage to the rim.

However, there are lot of RFT fan around who are happy with these.

Yup, all this too, horrible ride. I could go on and on. I have Summer non-runflats now and if anyone wants to feel the difference, go from all season runflats to summer softy non runflats and you will be in heaven,

I am sooo looking forward to this ^.

I have a 19" square set up currently on my 540 and looking to buy another set of wheels for summer. My preference would be 20" staggered and non-RFT's. The 19's I have now will get snows put on them in a month or so. Tires and wheels are one of those things the more you research the less you know! lol

I didn't see a specific answer to this question, so I will answer based on my experience. Getting tires, even tires your BMW dealership doesn't sell, will not void your warranty. I have a second set of 668Ms with Continental DWS06 for the winter (wheels bought from eBay in 2018, tires from TireRack and installed at local indy Bimmer shop). Had the tire replaced under wheel/tire. I put my summer tire on, dropped off the flat DWS06 wheel at the dealer, and they replaced it no issues. The only problem was that since it wasn't a tire offered by BMW, they had to order it (which is why I just dropped off the wheel - so I wouldn't be without a car for a few days).

[Mag_Ice_DL]

Just a few more words about how different is the drive on RFT and non-RFT tyres.

I have a staggered summer tyre setup 245/45 & 275/35. Today I replaced my 2-3 years old runflats Goodyear Eagle F1 Assy 3 due to unequal wear in the front. Rear tyres were not that bad, but due to xDrive, I swop all 4 to keep it safe and easy.

I fitted non-RFT Michelin PS4 ZR with the same sizing.

I new that I will notice big difference as I made similar swap before on a couple of previous cars. But this time I was shocked how much different these are! The drive is just so much better!!! It's smooth, I can feel any movement, and turn of my car, control and cornering is just perfect and it's all with far less road noise and greater, far greater comfort as you don't feel every single imperfection of the road while cruising.

Having read so much here, and been in my friends 5 with RF, I knew I was not going to get along with them.
Mine came with 20" rims and RF tyres.
They got swapped out on day 2 for 19" with Conti 7's summer. non RF.
Difference is not just 'marked' but quite profound in my opinion, so, so much better and incredibly comfortable, even on less than perfect road surfaces.
I will not be going back to RF, but being a PHEV, I have no room for a spare or space saver spare, so multiple things in the boot to try and keep me going in the event of a flat.
